See main article: Boxing at the 1998 Asian Games.
The men's light welterweight boxing competition at the 1998 Asian Games in Bangkok, Thailand was held from 9 to 18 December at the Land Sports Complex.[1]
Like all Asian Games boxing events, the competition was a straight single-elimination tournament. This event consisted of 16 boxers. The competition began with the round of 16 on 9 December, where the number of competitors was reduced to 8, and concluded with the final on 18 December. Both semi-final losers were awarded bronze medals.
All bouts consisted of five three-minute rounds. The boxers receive points for every successful punch they land on their opponent's head or upper body. The boxer with the most points at the end of the bouts wins. If a boxer is knocked to the ground and cannot get up before the referee counts to 10 then the bout is over and the opponent wins.
